COMBINED GAS AND AIR MIXER AND BURNER.

This invention relates to low pressure gas and oil burners and particularly tov means .for mixing the gas or vapor and air and burning the same.

The general object of the present invention is to'provide a construction of this kind including a relatively large chamber into which air and gas, preferably previously mixed, are introduced, this chamber being' provided with burner tubes extending therefrom opening preferably adjacent the bottom of the chamber whereby the mixed gas and air may be burned.

My invention is illustrated in the accompanying drawings, wherein:-

Figure 1 is a vertical longitudinal-section through a gas mixer and burner constructed in accordance with my invention; 1

Figure 2 is a section on the line 22 of Figure 1.

Referring to these drawings 10 designates a chamber of any suitable material which may, for instance, have the form of a barrel andis closed at its opposite ends but provided with an inlet opening 11. This is connected to a source of air and gaspreferably.

under low. pressure. Preferably this gas and air will be previously mixed in anysuitable air and gasmixer and led by a pipe 12 into the chamber through the opening 11. Extending into the chamber through the top thereof are a plurality of burner pipes 13. These pipes extend below the center of the chamber and have their lower'ends disposed relatively adjacent to the bottom of the chamber. Preferably there will be two rows of these pipes 13 extending downward into the chamber in convergent relation. There may be one row of these pipes 13 or more than two rows if desired. I

By conducting the gas and air into this relatively large chamber, even if the gas and air have not been previously mixed, I secure in practice a Application filed NovembetlS, 1926. Serial No. 149,161.

This secures a V The chamber 10 is adapted to be detached or connected to any air and It will be noted that the inlet pipe 11 is disposed adjacent the top of the barrel or receiving chamber and this inlet pipe may be disposed either at one end of the chamber or in the middle thereof, as illustrated. The small pipes 13 extenddownward quite close to the bottom of the chamber.

The gas is mixed thoroughly at the upper part of the chamber before the mixed air and gas sinks ber and thus forces the light air and gases through the burner tubes,-securing a very high degree of combustion and a hot fire.
